Air washers with 90% evaporation efficiency and 2-stage IDEC evaporative cooling units. 2,000 to 40,000 CFM. No refrigerant required.
An evaporative air cooling unit (also known as an air washer or industrial evaporative cooler) cools air using the principle of adiabatic evaporation — hot ambient air passes through water-saturated cellulose or honeycomb pads, causing water molecules to evaporate and absorb heat energy from the air, reducing its temperature by 10–15°C. This natural process requires no compressor and no chemical refrigerant, making it 80–90% cheaper to operate than mechanical refrigeration (vapor compression). Advanced 2-stage IDEC (Indirect-Direct Evaporative Cooling) adds a first stage where air is pre-cooled through a dry heat exchanger without adding moisture, achieving supply temperatures closer to the dew point.
Aerotech's Air Cooling Units provide energy-efficient cooling without chemical refrigerants. Our floor mounted air washers achieve up to 90% evaporation efficiency using high-saturation cellulose cooling pads with FRP/SS water basins. The 2-Stage Indirect/Direct Evaporative Cooling (IDEC) units deliver up to 40% energy savings compared to conventional air conditioning — no compressor, no ozone-depleting chemicals. Capacities from 2,000 to 40,000 CFM. Applications include textile mills (humidity control), manufacturing plants, warehouses, data centres (driving PUE toward 1.0), banquet halls, and food processing facilities. Water conservation: saves up to 30% versus traditional evaporative systems.
An evaporative air cooling unit (also called an air washer or desert cooler in industrial context) works on the principle of adiabatic cooling — hot dry air is passed through water-saturated cellulose pads, causing water to evaporate and absorb heat from the air, reducing its temperature by 10–15°C without any compressor or refrigerant. This makes evaporative cooling 80–90% cheaper to operate than mechanical refrigeration. Advanced 2-stage IDEC (Indirect-Direct Evaporative Cooling) systems add a first stage where air is pre-cooled without moisture addition through a heat exchanger, achieving temperatures closer to the dew point.
Aerotech manufactures air washer units (floor mounted, 2,000–40,000 CFM) and advanced 2-stage Indirect-Direct Evaporative Cooling (IDEC) units (3,000–40,000 CFM). Our air washers achieve up to 90% evaporation efficiency with high-saturation cellulose pads and FRP/SS water basins. No refrigerant, no compressor — only water and fan power for extremely cost-effective cooling.
The IDEC system combines indirect cooling (polymer heat exchanger lowers temperature without adding moisture) with direct evaporative cooling, delivering up to 40% energy savings versus conventional AC and 30% water savings versus traditional systems. Suitable for manufacturing plants, textile mills, auditoriums, banquet halls, food processing, and pharmaceutical facilities.
